Basilosauridae

Basilosauridae is synthesized as a sampled late Eocene radiation of fully aquatic archaeocetes with several distinct genera; the family grouping does not imply that every basilosaurid lies on the direct ancestry of Neoceti. This navigation entry is not a phylogeny or a complete taxon dossier.

Basilosauridae is displayed at 41–34 Ma only as the review's sampled late-Eocene radiation, not exact family FAD/LAD. The interval is a source-bounded sample window, not a global FAD, LAD, divergence date, continuous occupancy claim or direct-ancestor assertion.
